Thysanoptera: Phlaeothripidae): Redefinition and Key to Species
The southern Palaearctic genus Neoheegeria (Thysanoptera: Phlaeothripidae): redefinition and key to species Kambiz Minaei, Parvaneh Azemayeshfard & Laurence A. Mound Problems in character state definition and interpretation in the Haplothrips-group are discussed, together with their implications for species identification and systematics. As a result, Neoheegeria Schmutz, 1909 is redefined to include only those species in this group that have three sensoria on the third antennal segment. The subgenus Haplothrips (Gigaplothrips) Priesner, 1949 is synonymised with Neoheegeria, and four species are recognized as valid; N. dalmatica Schmutz, 1909, N. gigantea (Priesner, 1934) comb.n., N. persica Priesner, 1954, and N. sinaitica Priesner, 1934. Three new synonyms are recognized under N. dalmatica; N. ballotae Priesner, 1951, N. hamanni Priesner, 1961 and N. nevskyi Moulton, 1946, and this species is widely distributed in the southern Palearctic. In contrast, N. persica and N. sinaitica are known only from Iran and Egypt respectively, and N. gigantea from Egypt to Morocco. The following six new combinations involve species with less than three sensoria on the third antennal segment: Haplothrips biroi (Priesner, 1928), H. faurei (Zur Strassen, 1966), H. hrasvamukha (Ramakrishna, 1928), H. johni (Priesner, 1925), H. lederi (Priesner, 1924), and H. verbasci (Osborn, 1897). One new combination involves an unrelated species from India, Xylaplothrips montanus (Ananthakrishnan & Jagadish, 1970). The available biological data suggest that species of Neoheegeria are associated particularly with the flowers of Lamiaceae. K. Minaei * & P.

(“EGP”) closed the sale to power company Atlantica Yield of its fully-owned subsidiary Enel Green Power Uruguay S.A. (“EGP Uruguay”), which owns through its project company Estrellada S.A. the 50 MW Melowind wind farm located in Cerro Largo, around 320 km away from Montevideo. EGP has sold its subsidiary in Uruguay for around 120 million US dollars, equal to the company’s Enterprise Value. The transaction is part of the disposal programme of non-core assets provided for in the Enel Group’s active portfolio management plan. This strategy allows for the reallocation of resources to areas with a greater growth margin and potential for the Group. The Melowind farm sells its electricity output to the state-owned power company UTE (Administración Nacional de Usinas y Trasmisiones Eléctricas), which manages the transmission, distribution and sale of electricity in Uruguay, under a 20-year power purchase agreement (PPA). Atlantica Yield plc owns a diversified portfolio of contracted renewable energy, efficient natural gas, electric transmission and water assets in North and South America, and certain markets in Europe, the Middle East and Africa (EMEA). -

Plants belonging to the Scorzonera genus have been a significant part of folk medicine in Asia, especially China, Mongolia, and Turkey for centuries. Therefore, they have become the subject of research regarding their phytochemical composition and biological activity. The aim of this review is to present and assess the phytochemical composition, and bioactive potential of species within the genus Scorzonera. Studies have shown the presence of many bioactive compounds like triterpenoids, sesquiterpenoids, flavonoids, or caffeic acid and quinic acid derivatives in extracts obtained from aerial and subaerial parts of the plants. The antioxidant and cytotoxic properties have been evaluated, together with the mechanism of anti-inflammatory, analgesic, and hepatoprotective activity. Scorzonera species have also been investigated for their activity against several bacteria and fungi strains. Despite mild cytotoxicity against cancer cell lines in vitro, the bioactive properties in wound healing therapy and the treatment of microbial infections might, in perspective, be the starting point for the research on Scorzonera species as active agents in medical products designed for Citation: Lendzion, K.; Gornowicz, miscellaneous skin conditions. -

Received: 27 May 2018; Accepted: 30 July 2018; Published: 3 August 2018 Abstract: Zircon U–Pb dating and Hf isotopic analyses are performed on clastic rocks, sedimentary tuff of the Dongchuan Group (DCG), and a diabase, which is an intrusive body from the base of DCG in the SW Yangtze Block. The results provide new constraints on the Precambrian basement and the Late Paleoproterozoic to Mesoproterozoic tectonic evolution of the SW Yangtze Block, South China. DCG has been divided into four formations from the bottom to the top: Yinmin, Luoxue, Heishan, and Qinglongshan. The Yinmin Formation, which represents the oldest rock unit of DCG, was intruded by a diabase dyke. The oldest zircon age of the clastic rocks from the Yinmin Formation is 3654 Ma, with "Hf(t) of −3.1 and a two-stage modeled age of 4081 Ma. Another zircon exhibits an age of 2406 Ma, with "Hf(t) of −20.1 and a two-stage modeled age of 4152 Ma. -

Algerian Inuleae Tribe Species Distribution Modeling Under Influence of Current and Future Climate Conditions

This study aims to predict the impact of bioclimatic variables in current and future climatic scenarios on the distribution of Inuleae tribe species. Modeling the distribution of 30 species of the Inuleae tribe in Algeria was carried out with a maximum entropy model. Two models with 99 occurrence points were obtained with mean values of Area Under a Curve (AUC) of 0.987±0.01 and 0.971±0.02, reflecting excellent predictive power. Three bioclimatic variables contributed mainly to the first model and four - to the second one with cumulative contributions of 83.8% and 79%, respectively elucidating differences between species of the two major climatic zones in Algeria: the Tell and the Sahara. Two-dimensional niches of Algerian Inuleae species allowed to distinguish these two groups with the distribution of 18 Tell species, characterized by high rainfall (14-18°C, 400-1000 mm) and the other 12 species – distributed in hot and dry environments (17-24°C, 20-200 mm). Modeling the distribution under future conditions showed that habitats of the Saharan region would be much less suitable for these species with a variation in the annual mean temperature increase up to 20% and a decrease in annual precipitation, which could raise to 11 and 15%. -
